Abstract
An improved carpet tack strip formed from synthetic chemical and natural materials which include a selective amount of a polyethylene material of between 40% to 60% by weight, which is mixed with a selected amount of polypropylene material having about 1% to 10% by weight and including therein a fine powdered wood material having a selected amount of between 60% to about 40% by weight, wherein the mixture thereof is extruded from an extruding apparatus, thereby producing a continuous elongated homogeneous plastic strip that when cooled is cut in predetermined lengths.
Claims22
A process of forming an improved carpet tack strip that is adapted to support a plurality of substantially equally spaced tack members, wherein said carpet tack strip is formed from a plurality of synthetic chemical materials and natural materials that are mixed and extruded from an extruding means to define a continuous elongated plastic strip which when cooled is cut in selective lengths, whereby said process comprises the steps of:
- mixing a selected amount of a polymerized ethylene resin within a hopper of said extruding means;
- mixing a selected amount of thermoplastic resin together with said polymerized ethylene resin in said hopper;
- mixing a selected amount of a powdered wood product together with both said thermoplastic resin and said polymerized ethylene resin in said hopper,
- extruding the mixture and thereby producing a continuous elongated extruded homogeneous structure;
- cutting said elongated extruded homogeneous structure, and, before or after said step of cutting, attaching a plurality of tack members to the homogeneous structure to form a carpet tack strip having a predetermined selective length.
An improved carpet tack strip supporting a plurality of equally spaced tack members, wherein said carpet tack strip is formed from a plurality of synthetic chemical materials that are mixed together in a hopper and extruded from an extruding means to define a continuous elongated plastic strip which when cooled is cut in selective lengths, whereby said carpet tack strip further comprises:
- a selected amount of a polymerized ethylene resin;
- a selected amount of thermoplastic resin mixed together with said polymerized ethylene resin in said hopper;
- a selected amount of a powdered wood mixed together with both said thermoplastic resin and said polymerized ethylene resin in said hopper of said extrusion means, thereby producing a continuous elongated extruded homogeneous structure, and wherein said elongated extruded homogeneous structure is cut in predetermined selective length to provide a multiplicity of individual carpet tack strips.
